I have loaded the update for NVIDIA graphic card (Display Driver 257.21) and PE 7.5 will not open. I have been using the programs with no problems except the usual crashes, and never could burn to disc. The Photoshop will load OK. Any suggestions? Cindy

I was not aware that there was a point upgrade for PrE 7 released. I did not even recall a dot update release. Where did you get PrE 7.5 from?

As for the nVidia driver, what happens when you roll-back to an earlier video driver? I always keep several on my system, as some of the newest ones have caused a few problems with different programs.

If necessary, you can do a manual System Restore Point (for now), and then reboot to Safe Mode, and choose a System Restore Point before the update. What happens then?

As for crashes and not being able to burn to DVD, I would suggest posting much more info on your system, Projects and assets. This ARTICLE will give you tips. Specifically for the DVD burner issue, this ARTICLE might be useful.
